Procedure

To a solution of (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-1-(4-bromo-2-(3-methyl-1H-pyrazol-1-yl)phenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate (300 mg, 0.388 mmol, see Example 1u) in EtOH:H2O (15 mL) was added 4,4,5,5-tetramethyl-2-vinyl-1,3,2-dioxaborolane (90 mg, 0.58 mmol), KHCO3 (389 mg, 3.88 mmol), and PdCl2(PPh3)2 (41 mg, 0.058 mmol). The reaction mixture was heated to 80° C. for 1 h, then cooled to RT. The reaction was diluted with water, extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification with a 40 g Isco RediSep silica cartridge (EtOAc:heptane) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-2,2,2-trifluoro-1-(2-(3-methyl-1H-pyrazol-1-yl)-4-vinylphenyl)ethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2,3-dicarboxylate as a white solid.
